Gives my truck more power. Have not had it on long enough to see if gas mileage improves.

We purchased this air filter kit while travelling, we haul a 30' RV and were going across Canada. Unfortunatly there was a small defect in one area, which prevented it from being installed immediately. We needed to get on the road, so we informed K&N of the problem (with pictures) and when we returned home the part was already waiting for us. The difference in power with this new air filter is awesome. We drive a 2006 F350 6L 4x4 Superduty. Great service, Thanks
